Increase of ABL Revolver

On June 14, 2013, we entered into an amendment (the “Amendment”) of our previously disclosed first-lien senior secured credit agreement (and related agreements) entered into on May 2, 2013 (the “ABL Revolver”) with Wells Fargo Bank, National Association (“Wells Fargo”), as Administrative Agent, Lead Arranger, Book Runner, Syndication Agent, and Documentation Agent, and other lender parties thereto. Among other changes primarily to align the ABL Revolver with our business following our recent acquisition of Evergreen Helicopters, Inc., the Amendment increases the maximum aggregate amount that we can borrow under the ABL Revolver at any one time from $100.0 million to $125.0 million.

In connection with the ABL Revolver, on June 14, 2013, we entered into a joinder (the “Joinder”) to the Guaranty and Security Agreement and Intercompany Subordination Agreement (the “Guaranty and Agreements”) with Wells Fargo (as agent for the lenders). The Joinder adds our subsidiary Evergreen Unmanned Systems, Inc. as a party to the Guaranty and Agreements.

To secure our obligations under the ABL Revolver, on June 14, 2013, we entered into a line of credit deed of trust, assignment of rents and leases, security agreement and fixture filing (the “First Lien DOT”) with the Chicago Title Insurance Company (the “Trustee”) and Wells Fargo, as administrative agent for the lender group (the “First Lien Beneficiaries”). The First Lien DOT grants the Trustee, for the benefit of the First Lien Beneficiaries, a first position security interest in land, improvements, fixtures, leases, rents, and other trust property we own as set forth in the First Lien DOT.

As previously disclosed, on May 2, 2013, we entered into an indenture, pursuant to which we issued $400.0 million in aggregate principal amount of 8.25% Second Priority Senior Secured Notes due 2020, and a related Security Agreement (the “Security Agreement”). On June 14, 2013, we entered into a line of credit deed of trust, assignment of rents and leases, security agreement and fixture filing (the “Second Lien DOT”) with the Trustee and Wilmington Trust, National Association (“Wilmington Trust”), as collateral agent for the secured parties under the Security Agreement (the “Second Lien Beneficiaries”). The Second Lien DOT grants the Trustee, for the benefit of the Second Lien Beneficiaries, a second position security interest in land, improvements, fixtures, leases, rents, and other trust property we own as set forth in the Second Lien DOT.

A copy of the Amendment, the Joinder, the First Lien DOT and the Second Lien DOT are attached hereto as Exhibits 10.1, 10.2, 10.3 and 10.4, respectively, and are incorporated herein by reference. The descriptions of the Amendment, the Joinder, the First Lien DOT and the Second Lien DOT in this current report are summaries only and are qualified in their entirety by the terms thereof.
